Accordingly, it is very important to control the operation of the air supply unit.
  • a dry time is determined in the conventional laundry treating apparatuses based on a dry course which is selected by a user. If a large amount of clothes are loaded, the dry level of the clothes might fail to reach a reference dry level (in other words, a dry performance might be low) disadvantageously.
  • the conventional laundry treating apparatus is likely to have a disadvantage of energy waste which might be caused by the operation of the air supply unit during the dry time set in an early stage even after the dry level of the clothes reaches the reference dry level. It is an object to provide a method to control a laundry treating apparatus and to provide a respective control apparatus.
